Growing up in New Delhi, I remember that electricity and water were dependable commodities in the early part of my childhood. Around age ten, after my parents had moved to a house in a newer part of Delhi, trouble with water and electricity (mostly water) first made itself felt in our lives. Uninterrupted and dependable supply of water was no longer a given. Gradually, things became so bad that water rationing and planning our lives around when "water would flow from the faucets," became a daily routine. Early in the morning, adults of the household would become busy for an hour or so, filling up various receptacles with water for the entire day’s use. The containers were designated with varying degrees of purity and cleanliness. Drinking water was stored in clean, covered containers in or near the kitchen. Water for non drinking purposes was stored in drums, buckets and assorted vessels kept near bathrooms, in the courtyard etc. Everyone needed to finish with shower and bathroom activities by 9am. We had to work fast and with consideration for the next bather because by 9:30am the water turned into a trickle and by 10, it was gone – only to show up reluctantly, around 5pm when another round of frantic flurry of "fill the pots" would begin. We grudgingly learnt to live with water paucity which was especially hard and annoying during the relentlessly scorching summer months. The problem was universal – it did not matter whether one lived in a rich or a poor neighborhood. It did not escape our notice however that parts of New Delhi where members of the Indian Parliament (equivalent of the members of our Congress) and highly placed government officials lived, did not experience difficulty with their water supply!
Things only got worse in the ensuing years. Citizens waited patiently for a couple of decades for the government to turn things around. When nothing improved, they took matters in their own hands. Most homes and apartment owners and builders have taken to digging deep underground wells in their backyards to draw water into rooftop storage tanks. It is now common practice in most big and mid-sized cities. That ensures a continuous supply of water. However, the do-it -yourself approach to solving problems of public utilities comes at a high cost. Pumping underground water for daily use, as also the frequent use of diesel generators to produce electricity during wide spread power cuts at all hours of the day and night have contributed to air pollution and alarming depletion of the ground water table, which do not bode well for India’s environmental integrity. To make matters worse, the quality of the water that the government does manage to pipe into homes and businesses, leaves much to be desired in terms of its safety and potability. Suspicions of raw sewage mingling with the drinking water supply has plagued the Delhi municipality for years. Most people use commercial filters and many boil their drinking water. Ground water too is no longer deemed safe due to increased levels of contaminants such as mercury and arsenic. The water situation in India is indeed dire.
Recently The New York Times ran an article about uncontrolled and devastating floods in India. The article points to the irony of a country caught between two untenable scenarios due to poor planning and a government indifferent to the basic needs of citizens. One, the dire lack of clean water for human consumption and the other, an overabundance of water in the form of rain and flood which first destroys and then goes to waste. It makes eminent (and imminent) sense to harvest some of the wasted water for human use and preserve and replenisht the rapidly sinking natural ground water table.
Sanjay Garg, a reader and fellow blogger who is knowledgeable about issues relating to economic and other developments around the world (especially India) sent me a fact filled article enumerating the steps India could take (and is taking) to correct its long festering water woes. (Thanks, Sanjay.) But as with everything else in India, I will wait to see how many of these sensible solutions are actually put into practice without corruption, scandal or gross mismanagement. I don’t want to sound a pessimistic note and I hope that all the steps that Sanjay has listed are indeed put into practice efficiently and without delay. After all, if Israeli scientists could make the desert bloom, India should be able to harvest, channel and deliver clean water to all its citizens.
Note: This is a rather long post and may not be of particular interest to some of the readers. But it happens to be a topic that I deeply care about. That is why I invited Sanjay who has many facts and data at his fingertips, to contribute to this article. I have attached a painting of mine here which I had previously published in another post. The seemingly peaceful picture of the two women walking gracefully through an arid field, actually represents a brutal reality of rural India. Women walk miles, twice a day, just to draw water for daily use. It is a backbreaking task, more so because rural women are all "working" women who toil at home and in the fields all day.
Sanjay says the following:
"India is actually blessed by nature with bountiful water – it is amongst the ‘wettest’ countries in the world, yet ‘desert-like’ conditions are now prevalent in many parts of the country. Even states like Kerala with 44 rivers, copious lakes, and 3000 mm rainfall, faces an acute water crisis in the near future. Overall in India, 50% of the people do not have free access to safe drinking water. I have my own analysis of the root causes for this state of affairs but this perhaps is not the place to delve into it.
The largest single use of fresh water in India is for irrigation purposes – 80% of all fresh water drawn. The other 20% is for personal & industrial use. Rainfall being unpredictable & piped municipal water supply deemed expensive, people keep drawing on Ground water to meet their fresh water needs. To the extent that almost 2/3rd of the total fresh water used is drawn from the water table. Ground water thus plays a significant role in sustaining both the general development and economic growth of the country.
Increasing pace of ground water depletion in order to meet the growing demands of water in agriculture, industrial and domestic sectors, has brought problems of over-exploitation, declining water levels, seawater ingress in coastal areas and ground water pollution in different parts of the country. The falling ground water levels in various parts of the country threatens the sustainability of ground water resource, as water levels have gone deep beyond the economic lifts of pumping. The speedy and uncontrolled depletion of ground water resources has resulted into increase in over-exploited and critical dark blocks.
Over the past decade, there has been increasing realization of the depleting ground water problem. Natural recharge of ground water being a very slow process, efforts are underway to supplement it with "artificial" recharge i.e. via rainwater harvesting. A number of programs have been initiated for water conservation and rain water harvesting through central & state govt. agencies. There are states where rain water is harvested in every house like Mizoram in northeast India. In Rajasthan and Gujarat, which are drought prone states, people are increasingly realizing the importance of rain water harvesting. As a result of this awareness, these states have been able to achieve significant improvement in the availability of water for drinking and other purposes. Voluntary organizations and individuals have also contributed significantly in promoting rain water harvesting.
Last week, The Central Ground Water Authority (CGWA) issued directives to the state governments to take up all measures to adopt artificial recharge to ground water and promote rain water harvesting in all the over-exploited and critical areas. The directive also is aimed at ensuring inclusion of roof top rain water harvesting in the building bye-laws. Further, the CGWA has also issued directions to housing societies, institutions, hotels, industries, farm houses, etc., in the notified areas where ground water table is below 8 meters from ground surface to adopt rain water harvesting system.
Private industry is also getting involved in rainwater harvesting. Coca Cola (India), with technical guidance from the state of Uttar Pradesh (where Ground water is depleting at 51 cms annually) has initiated a rain water harvesting project. Coca Cola had already commissioned 5 rain water harvesting projects, with the capacity to recharge 3000 cubic metres annually. The company will set up another such project at the environment ministry premises next week.
In addition to rainwater harvesting, efforts are on for water purification, water de-toxification, water desalination through nano membranes and nano sensor for detecting contaminants and pathogens. Scientists from Banaras Hindu University have devised a simple method to produce carbon nanotube filters that efficiently remove micro-to nano-scale contaminants from water. India is endowed with a long coastline with many densely populated urban areas along the coastline and desalination is a distinct possibility if cost & technology-feasible. It may be possible to provide desalinated seawater for drinking purposes to these coastal cities and towns, utiling nuclear-powered desalination plants on floating barges at a reasonable cost. A pilot desalination project is currently operating in the southern coastal area of Tamil Nadu.
On the scale of "hard-to-do" fresh water projects, the toughest and farthest reaching is the river-linking proposal. It is based on the idea of transfering water from excess supply to deficit areas. As an example, for two months of a typical year, the Brahmaputra River carries more water by volume than all the rest of Indian rivers combined. If even 10% of this flow could be diverted away from the Brahmaputra, it will not only meet the fresh water needs of the rest of India but reduce floods in the east."
